Design Pitch Control Mechanism for Small Wind Turbine

The aim of this project is to design and manufacture a prototype for a pitch control mechanism to be fitted to small horizontal axis wind turbine competing in the International Small Wind Turbine Contest (ISWTC) held in the Netherlands in Summer 2022. The pitch control mechanism should be able to handle the following loads: 1. Force in the span-wise direction (pulling the blade in the direction of the centrifugal force) = 600 N 2. Wind force on the blade (assumed to be concentrated in the middle of the blade = 130 N 3. Required Pitching Torque = 2.5 Nm The following Design Constraints should be considered: 1. Total length of the blade = 756 mm 2. Maximum Turbine rotor diameter = 1600 m 3. Total swept area = 2 m2 4. The mechanism is connected to the generator via 6 M8 Tap Bolts at PCD = 100 mm, with centering. 5. The blade should be rotated 0-90 Degrees. 6. The whole mechanism should be confined within the turbine nose. 7. The system should be operated by 12 Volt Battery. It can be tested using a power supply.
